1

Service the ABS system before diagnosing for a misfire, because an actual engine misfire may or may not exist. The following examples illustrate how this DTC can be set with or without an actual engine misfire:
- There was an actual engine misfire during an ABS system malfunction.
- The vehicle operator drove on a rough road, the ABS system could not detect this condition due to a malfunction, and the PCM interpreted the variations in the crankshaft speed caused by the rough road as a misfire.
